Patented Mar. 1, 1932 UNITED STATES? auromrrc 1T Application fled November 25, 1930, Serial No."49 8 )i0,"anr 1"in etrti nj iqtvi' niitetasj-ieza Automatic indicating targets are known, in which the projectile, either piercing the target or striking and repelled thereby, closes certain electric circuits indicating the position of the hit.

The invention difl'ers advantageously from these lmown arrangements in that the bullet remains adhering to the target and closes-hit indicating circuits, known per se, until the 10 bullet is ejected from the disc by a special mechanism operated from the firing point. This is effected in that the disc consists of two plates, the front plate being provided witlrperforations and adapted to be fiapped 1 down by a mechanical ull device an the rear plate being provide with rigid projecting pins corresponding in number to the number of holes in the front plate and registering with these holes in such a manner that the ins engage in the holes of the front plate an leave a certain" clearance so that the bullet in striking the target remains in this clearance. If the front late is flapped down, the bullet is pulled o the pins and a counterweight returnlng the flap ed down disc into its initial position on the pulling element being released.

'An embodiment of the invention is illus trated by way of example in the accompanying drawings, in which:

ig. 1 shows the target in front elevation.

Fig. 2 is a central vertical cross section of Fig. 1.

Fig. 3 shows the number box with connecting wires.

The target consists substantially of a steel disc a in which the individual rings are formed by bores b and contact pins d of a rear wooden plate 0, said contact pins (1 engaging each with a clearance in the bores b of the steel disc a, are fixed in such a manner that the pins of each ring are electrically connected to ether by contact rings 6, which are indivi ually insulated the ones against the others,

the ins d in the bores 12 slightly receding behin the front surface of the disc (1. The rings d are connected by means of wires 1 to 12 to the individual sources of light f of the corresponding number compartments of an indicating box g, a common return wire passmnr.

"A'lead'bullet iw" cliforex ample has entered a bore srtte g-ai sn-m nects the steel disc "a-to"the coiitictiii g e through the pin d situated therein-sextetthe sourcev of light of the compartment 7 illuminates the number 7 in the indicating box. If the lead bullet connects two bores of two oo neighbouring rings, the corresponding numbers of both rings will be illuminated. By means of the adhering bullet the marksman can see on the disc, where his bullet has bit. The contact pin (1, situated in the bulls-e e, is made hollow, and a space It is provided be ind this pin and separately illuminated so that the bulls-eye of the target'is indirectly illuminated for facilitating the taking of aim This source of light can be controlled by a o separate switch not shown in the drawings.

F or ejecting the adherin bullet, the steel disc at is him edly mounted on pins m so that by pulling t e elbow lever n in the direction of the arrow A, the disc a can be swung away from the contact pins to a stop 0, so that the bullet i is removed from the contact pins by shifting the disc (1 and drops out of the disc at when this disc strikes the stop 0. On the elbow lever n bein released, the steel disc a "a0 is returned into its initial position by a counterweight p.

In order to afford the contact pins d, a better hold in the wooden plate a and to impart a smooth bearing surface to the steel 86 disc a, a plate is arranged between the disc a and the woo en plate a, andfixed to this latter, which plate g may be made of hard insulating material.

I claim:

1. An automatic indicating target,inwhich certain electric circuits are closed by the bullet striking the targ'et, comprising in combination means for retaining the bullet in the L target and temporarily closing the corresponding circuit, and mechanical means for ejecting the bullet from the target adapted to be actuated from the firing position.

2. A target as specified in claim 1, comprising a disc made of sheet steel having rings composed of closely, juxtaposed bores, a plate arranged behind said steel disc, contact pins on said plate adapted to engage with play in the bores of said steel disc, mutually insu- 5 lated contact rings connecting the pins of the individual rings in said steel disc, and electric circuits one for each of said rings adapted to be closed when a bullet strikes one of said contact pins.

1 3. A target as specified in claim 1, comprising in combination a steel disc having rings formed by bores, a plate arranged behind said steel disc, contact pins on said plate engaging with play in the bores of said disc, a hinge pin 15 carrying said steel disc, an elbow lever adapted to swing said disc on said hinge pin, a pull element adapted to actuate said elbow ever, a stop adapted to arrest the movement of said steel disc, and a counterweight adapt- 20 ed to return said disc to its initial position on said pull element being released.

' In testimony whereof I afiix my signature.
